Percona Server 5.6.21-70.0 is now available

Percona is glad to announce the release of Percona Server 5.6.21-70.0 on October 30, 2014. Download the latest version from the Percona web site or from the Percona Software Repositories. We’re also happy to announce that Ubuntu 14.10 and CentOS 7 users can download, install, and upgrade Percona Server 5.6 from Percona’s software repositories.

Based on MySQL 5.6.21, including all the bug fixes in it, Percona Server 5.6.21-70.0 is the current GA release in the Percona Server 5.6 series. Percona Server is open-source and free. Complete details of this release can be found in the 5.6.21-70.0 milestone on Launchpad.

New Features:

• Percona Server has ported new super-read-only option from WebScaleSQL.
• Percona Server has implemented CSV engine mode for standard-compliant quote and comma parsing. This feature also fixes the bug #1316042 (upstream #71091).
• Percona Server now supports Read Free Replication for TokuDB storage engine.
• TokuDB storage engine package has been updated to version 7.5.2.

Bugs Fixed:

• Values of IP and DB fields in the Audit Log Plugin were incorrect. Bug fixed #1379023.
• Specifying the --malloc-lib during the server start would produce two LD_PRELOAD entries, if a system-wide jemalloc library was installed. Bug fixed #1382069.
• In multi-threaded slave replication setup, an incomplete log event group (the one which doesn’t end with COMMIT/ROLLBACK/XID) in a relay log could have caused a replication stall. An incomplete log event group might occur as a result of one of the following events: 1) slave crash; 2) STOP SLAVE or FLUSH LOGS command issued at a specific moment; 3) server shutdown at a specific moment. Bug fixed #1331586 (upstream #73066).
• Purging bitmaps exactly up to the last tracked LSN would abort XtraDB changed page tracking. Bug fixed #1382336.
• mysql_install_db script would silently ignore any mysqld startup failures. Bug fixed #1382782 (upstream #74440).

Other bugs fixed: #1369950, #1335590, #1067103, and #1282599.

UPDATE [2014-11-14]: Bug #1390695 caused Percona Server 5.6.21-70.0 to crash on data import on Ubuntu Utopic (14.10). This bug has been fixed and packages for Ubuntu Utopic have been updated.
